A cascading motion pattern was always observed in the absence of mill feed and with a typical ball filling ratio of 0.3. Nevertheless, by increasing the ball filling ratio or the friction conditions, due to the presence of the mill feed, the dynamics of balls changed to a cataracting regime.

The 531 Mills Mess is a variation of Mills Mess (or the 531 depending on your reference point) in which the balls are thrown in a tower pattern while your arms cross and uncross during each cycle. This adds a whole new layer of complexity and movement to the otherwise rigid 531, though the pattern itself is surprisingly easy to learn if your ...

Mills mess is a trick invented by Steve Mills. The pattern is a repeating sequence of three different kinds of throws: The first throw is an outside throw. The next catch made by the hand making this throw should be done with that arm crossed over the other arm. The second throw is made under the arm, and the arms stay crossed so that the next catch …

Then in ball-wear formula (25), T = 6.9/K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = 6.9Wt/Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/6.9Wt are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.

The mill liners used are constructed from cast alloy steels, wear-resistant cast irons, or polymer (rubber) and polymer metal combinations. The mill liner shapes often recommended in new mills are double-wave liners when balls less than 2.5 in. are used and single-wave liners when larger balls are used.

For 60 mm (2.5″) and smaller top size balls for cast metal liners use double wave liners with the number of lifters to the circle approximately 13.1 D in meters (for D in feet, divide 13.1 D by 3.3). Wave height above the liners from 1.5 to 2 times the liner thickness. Rubber liners of the integral molded design follow the cast metal design.
